Derek would have planted the tree 7 years ago. You subtract 36 from 44.75 and get 8.75. This is how much the tree grew since he planted it. Then, you'll divide 8.75 by 1.25 (1 1/4) which tells you how many years it has been since he planted the tree. The final answer is 7 years. Hope this helps!
If you mean average, then it's quite simple.
Usually when you want to find the average of something, you add them up all together and divide by how many there are.
For example, the numbers:
12, 69, 35, 67, and 2.
Steps:
1.) Add them. 12 + 69 + 35 + 67 + 2 = 185
2.) 185 divided by 5.
3.) Answer: 37
This is implying x = -3 so 18) 7 (-3) + 1 = -21 + 1 = -20 , 19) 7(8) + 1 = 56 + 1 = 57
Answer:
Step-by-step explanation:
−6 = −5⁄7[2] + b
−1 3⁄7
Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE RATE OF CHANGES [SLOPES], so 1 2⁄5 [or 7⁄5] becomes −5⁄7.

Step-by-step explanation:
I should be twelve because the lowest number is 4 then you add four and get 8 for T to U then there is a sixteen so they skipped twelve but four plus 12 equals 16 so x equals 12
